In all honesty. No. The pocket PC is another palm-like address book/note pad. The Newton is really a small computer with some really robust programs still available. I couldn't afford the Newton when it was first released so I've only been a Newton user for a year or two. That means I've had to learn how to adapt it to Mac hardware not designed for it. I've also had to search for available help and programs. What's neat is how large, active and helpful the newton community still is. I've even borrowed my wife's wireless pc card (D-link 650) and am in the process of setting it up to access our email with my Newton and airport. Palm's just getting around to that. The best part is, have you ever left a palm device in a desktop over a holiday weekend (or similar), come back and found out your batteries had died and everything you had input over the past month (and not backed up) was gone. That doesn't happen with the newton.
I bought the Jornada to use as a datebook and memo pad. Up until now, as a mac user, it hasn't even served well for that. I'm in a line of work where I've gotten to see or test drive most of the PDAs on the market. Even the notebook sized PDAs (like compaq's Aero). This one plays music, that one has a large screen and keyboard, this one has a camera adapter, that one uses a memory stick. Bottom line, they're all about the same and all very limited. Ever try to read a large text file or spreadsheet in a pocket PC? Might as well go to lunch while waiting for word CE or Excel CE to load it. Games? I've got lots of Newton games to play during business trips and they were all free downloads.
I don't want apple to enter the PDA market. I want apple to return with a Newton 3000. Something with the sophistication of the Newton built with today's technology, like firewire, built in hard drive, easy communication with a network. And real handwriting recognition (like the Newton MP 2000 already has). For a piece of hardware which has been out of production for 5 years, the Newton is still years ahead of the competition.
So the answer is no, nothing I have tried in the pocket pc line even comes close to the Newton. And since you can now pick up a Newton MP 2000 for less than the price of a Palm 100, I've got two.
